Robbers posing as police officers allegedly looted Rs 2 crore under the guise of a raid at a businessman’s office in South Kolkata on Friday, much like in the Bollywood movie Special 26.

According to the police, the robbers introduced themselves to the businessman as police detectives and claimed they were searching his Pratapaditya Road office for a huge amount of unaccounted money that they had information was kept there.

They first flashed fake identity cards and then confiscated the mobile phones of the businessman and his employees, said the police.

The robbers threatened the staff, interrogated them about the cash in the office and learnt that it was kept inside a vault. They forced the staff to open the vault and fled with Rs 2 crore, according to the police.

A few hours later, after speaking to the local police, the businessman and his staff realised they had been targeted by a gang of robbers.

A complaint was subsequently lodged at the Tollygunge police station. On Saturday, the police arrested one suspect and recovered Rs 5 lakh from his possession after a raid on the outskirts of the city.

The police said they identified the robbers by analysing footage from CCTV cameras installed in the area.

Based on the arrested suspect’s interrogation, the police have launched a hunt for his accomplices and are trying to recover the rest of the looted money.

The detective department of the Kolkata police is also part of the investigation.
